<h1>Storage and eXchange Format - SXF</h1>

(GDAL/OGR >= 1.10.2)<p>

This driver reads SXF files, open format often associated with Russian GIS Software Panorama.<p>
The driver is read only, but supports deletion of data source. The driver supports SXF binary files version 3.0 and higher.<p>
The SXF layer support the following capabilities:
<ul>
<li> Strings as UTF8
<li> Random Read
<li> Fast Feature Count
<li> Fast Get Extent
<li> Fast Set Next By Index
</ul>
The driver uses classifiers (RSC files) to map feature from SXF to layers. Features that do not belong to any layer are put to the layer named "Not_Classified". The layers with zero features are not present in data source.<p>
To be used automatically, the RSC file should have the same name as SXF file. User can provide RSC file path using config option <b>SXF_RSC_FILENAME</b>. This config option overrides the use of same name RSC. <p>
The RSC file usually stores long and short layer name. The long name is usually in Russian, and short in English. The <b>SXF_LAYER_FULLNAME</b> config option allows choosing which layer names to use. If SXF_LAYER_FULLNAME is TRUE - the driver uses long names, if FALSE - short.<p>
The attributes are read from SXF file. Maximum number of fields is created for the same layer features with different number of attributes. If attribute has a code mapped to RSC file, driver adds only the code (don't get real value from RSC, as the value type may differ from field type).<p>
If config option  <b>SXF_SET_VERTCS</b> set to ON, the layers spatial reference will include vertical coordinate system description if exist.<p>
